AIM To evaluate the relationship between system delay and 30-day and long-term mortality in patients with anterior versus non-anterior ST-elevation myocardial infarction (STEMI). METHODS We conducted a prospective observational cohort study. Patients with STEMI who were transported to the Isala Hospital, Zwolle, and underwent primary percutaneous coronary intervention (pPCI) from 2005 until 2...
OBJECTIVE To investigate the associations of serum total and HDL cholesterol with the risk of myocardial infarction in men and women of 55 years and over. DESIGN The Rotterdam Study is a population-based prospective cohort study. In total 2453 men and 3553 women of 55 years and older were included in this study. The mean duration of follow-up was 4 years. MAIN OUTCOME MEASURES Relative risk...
BACKGROUND Exercise is associated with changes in circulating B-type natriuretic peptide (BNP) and N-terminal-proBNP (NT-proBNP). However, the biological relevance of this phenomenon is poorly examined. We sought to assess determinants of absolute (Δ) and relative (Δ%) exercise-induced changes in BNP and NT-proBNP. METHODS BNP (n = 418) and NT-proBNP (n = 478) at rest and peak exercise were m...
A Search for EUV Emission from Comets with the Cosmic Hot Interstellar Plasma Spectrometer ( CHIPS )
– 2 – We have obtained EUV spectra between 90 and 255Å of the comets C/2002 T7 (LINEAR), C/2001 Q4 (NEAT), and C/2004 Q2 (Machholz) near their perihelion passages in 2004 with the Cosmic Hot Interstellar Plasma Spectrometer (CHIPS). We obtained contemporaneous data on Comet NEAT Q4 with the Chandra X-ray Observatory ACIS instrument, marking the first simultaneous EUV and X-ray spectral observat...
OBJECTIVE Hyperglycemia is related to stroke. Glycated hemoglobin (HbA1c) can reflect pre-stroke glycaemia status. However, the information on the direct association between HbA1c and recurrence after non-cardioembolic acute ischemic strokes is rare and there is no consistent conclusion. METHODS The ACROSS-China database comprised of 2186 consecutive first-ever acute ischemic stroke patients ...
Exercise systolic blood pressure (SBP) predicts coronary heart disease (CHD) in the general population. We tested whether changes in exercise SBP during 7 years predict CHD (including angina pectoris, nonfatal myocardial infarction, and fatal CHD) and mortality over the following 28 years. Peak SBP at 100 W workload (=5.5 METS [metabolic equivalents]; completed by all participants) was measured...
OBJECTIVES To evaluate the association between sex-specific serum high sensitive C reactive protein (hsCRP) levels and NAFLD in a large population-based study. RESULTS From Q1 to Q4, the incidence ratios were 21.1 (95% CI 17.5 24.7), 18.6 (95% CI 16.5 20.8), 24.8 (95% CI 22.4 27.2) and 31.1 (95% CI 28.5 33.6) in males and 6.2 (95% CI 4.4 8.0), 6.0 (95% CI 5.1 7.1), 11.4 (95% CI 9.2 13.7) and ...
BACKGROUND Factors contributing to chronic inflammation appear to be associated with increased risk of ovarian cancer. The purpose of this study was to assess the association between circulating levels of inflammation mediators and subsequent risk of ovarian cancer. METHODS We conducted a case-control study of 230 cases and 432 individually matched controls nested within three prospective coh...
The aim of this study was to examine the association between sex-specific serum uric acid (sUA) levels and NAFLD in a large population-based study.A total of 60,455 subjects from 2 separate medical centers were included. Sex-specific sUA quartiles (Q1-Q4) were defined: ≤330, 331-380, 381-435, and ≥436 μmol/L for male; ≤230, 231-270, 271-310, and ≥311 μmol/L for female. The odds ratios (ORs), ha...
BACKGROUND We investigated whether prediagnostic reported intake of dairy products and dietary calcium is associated with colorectal cancer survival. METHODS Data from 3,859 subjects with colorectal cancer (42.1% male; mean age at diagnosis, 64.2 ± 8.1 years) in the European Investigation into Cancer and Nutrition cohort were analyzed. Intake of dairy products and dietary calcium was assessed...
